We're dividing 552115 by 21 
We want to figure out the number of times 552115 can be divided by 21.

On to step 1:
5 divided by 21 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 21

Going ahead to step 2:
If we divide 55 by 21, we get 2 and a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 42 away from 55, we end up with 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 21

Moving on to step 3:
When dividing 132 by 21, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
The remainder is 6 after subtracting 126 from 132.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 21

On to step 4:
21 goes into 61 2 times with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 262.0
Subtracting 42 from 61 leaves us with 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 21

Advancing to step 5:
21 goes into 191 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 2629.0
Deduct 189 from 191 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 21

Going ahead to step 6:
If we divide 25 by 21, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 26291.0
Deduct 21 from 25 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
When dividing 40 by 21, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 26291.1
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
190 divided by 21 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 26291.19
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
If we divide 10 by 21, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 26291.19
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
21 goes into 100 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 26291.1904
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
If we divide 160 by 21, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 26291.19047
If we take 147 away from 160, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
21 goes into 130 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 26291.190476
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
When dividing 40 by 21, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 26291.1904761
Subtracting 21 from 40 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 14:
If we divide 190 by 21, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 26291.19047619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 26291.19047619, and the remainder is 1e-09.
